Answer:
(x - 6)(x + 4) = 0.
Step-by-step explanation:
With your case of x2 - 2x - 24, we have b1+b2 = -2 and b1b2 = 1*(-24) = -24. So the equation x2 - 2x - 24 = 0 becomes (x - 6)(x + 4) = 0.
Answer:
very funny and 14
Step-by-step explanation:
0.7x-1.4=-3.5
Add 1.4 to both sides:
0.7x=-2.1
Divide 0.7 to both sides:
x=-3
2u = <-2, 4>
-v = <-3, 2>
3w = <0, -6>
I just multiplied each vector by its scalar, then added the components.
answer: <-5, 0>
